Abstract
Phytochemical investigation of the stems of Michelia compressa was performed by column chromatography. We isolated four aporphines, including (-)-anonaine (1), (-)-norushinsunine (2), (-)-ushinsunine (3), (-)-3-hydroxynornuciferine (4); one oxoaporphine, liriodenine (5); two amides, N-trans-feruloyltyramine (6), N-cis-feruloyltyramine (7); one lignan, (+)-syringaresinol (8); two neolignans, 2R,3S-dihydrodehydroconiferyl alcohol (9), 2S,3R-dihydrodehydroconiferyl alcohol (10); one benzenoid, vanillic acid (11), and two steroids, β-sitosterol (12) and stigmasterol (13) from the methanolic extract. The structures of these compounds were established on the basis of spectroscopic analysis.
